[Qgis-user] How to combine multiple rasters into a tilesarray?

[Nicolas Cadieux]

Hi,
I am not sure to understand but you can build a virtual raster (but I think you tried that?). I think there is a plugin also that can give you more options.  If not, you can use  command line to make sure you have the exact order of the files. The order of the files are from bottom to top except for null pixels.  QGIS 2.x gave you more options then QGIS 3.  :(.
